Description

Bei normaler Temperatur zerfällt SrCO[tief]3 in der gleichen Menge zu SrO und CO[tief]2, wie sich SrO und CO[tief]2 zu SrCO[tief]3 verbinden. Es herrscht ein Gleichgewicht.At normal temperature, SrCO [deep] 3 decomposes into SrO and CO [deep] 2 in the same amount as SrO and CO [deep] 2 combine to form SrCO [deep] 3. There is a balance.

Wird dieses Gleichgewicht durch Energiezufuhr verschoben, so zerfällt mehr SrCO[tief]3 als sich bildet. Das Gleichgewicht verschiebt sich zugunsten der energiereicheren Seite; es entsteht ein CO[tief]2-Überdruck.If this equilibrium is shifted by the supply of energy, more SrCO [deep] 3 decays than is formed. The equilibrium shifts in favor of the energetic side; a CO [low] 2 overpressure is created.

Kehrt man zur Normaltemperatur zurück, wird diese Energie wieder abgegeben. Es bildet sich mehr SrCO[tief]3 als zerfällt.When you return to normal temperature, this energy is released again. More SrCO [deep] 3 forms than decomposes.

Wird bei der Energiezufuhr CO[tief]2 abgesaugt bzw. durch den Überdruck durch ein Ventil abgeleitet, so findet eine Energiespeicherung statt, da das SrO infolge des fehlenden Bindungspartners nicht mehr zurückreagieren kann.If CO [deep] 2 is sucked off during the supply of energy or discharged through a valve due to the overpressure, energy is stored because the SrO can no longer react back due to the lack of a binding partner.

Kehrt man zur Normaltemperatur zurück und gibt das fehlende CO[tief]2 wieder hinzu bzw. läßt es durch den entstehenden Unterdruck wieder in die Kammer strömen, so reagiert SrO unter Energieabgabe zu SrCO[tief]3, bis das heterogene Gleichgewicht wieder erreicht ist.If you return to normal temperature and add the missing CO [low] 2 again or allow it to flow back into the chamber due to the resulting negative pressure, SrO reacts with energy release to SrCO [low] 3 until the heterogeneous equilibrium is reached again.

Beschreibung der Speichereinheit (siehe Zeichnung)Description of the storage unit (see drawing)

A = SpeicherwandA = storage wall

B = TrennwandB = partition

C = Raum für SrCO[tief]3C = space for SrCO [deep] 3

D = Raum für CO[tief]2D = space for CO [deep] 2

E = Ventil (C nach D), um Rückfluß zu verhindernE = valve (C to D) to prevent backflow

F = Ventil (D nach C), um Rückfluß zu verhindernF = valve (D to C) to prevent backflow

EnergiespeicherungEnergy storage

C wird erwärmt (E geöffnet, F geschlossen).C is heated (E opened, F closed).

Zerfall des SrCO[tief]3 in SrO + CO[tief]2; es entsteht ein CO[tief]2-Überdruck.Decay of SrCO [deep] 3 into SrO + CO [deep] 2; a CO [low] 2 overpressure is created.

Durch den Überdruck strömt das CO[tief]2 in die Kammer D, wo es gespeichert wird.Due to the overpressure, the CO [deep] 2 flows into chamber D, where it is stored.

Durch das fehlende CO[tief]2 kann in der Kammer C das SrO nicht mehr zurückreagieren.Due to the lack of CO [deep] 2 in chamber C, the SrO can no longer react back.

EnergiefreisetzungEnergy release

Ist die Normaltemperatur wieder erreicht, wird E geschlossen und F geöffnet.When the normal temperature is reached again, E is closed and F is opened.

Dadurch kann sich das CO[tief]2 wieder mit SrO zu SrCO[tief]3 verbinden - Energie wird frei.This allows the CO [deep] 2 to combine with SrO to form SrCO [deep] 3 - energy is released.

Claims (1)

Verwendung von SrCO[tief]3 als chemisches Wärmespeichermittel, das beim Erhitzen in SrO in CO[tief]2 zerfällt, welches in getrennten Kammern gespeichert werden und bei Bedarf unter Wärmeabgabe zu SrCO[tief]3 zurückreagiert.Use of SrCO [deep] 3 as a chemical heat storage medium which, when heated in SrO, breaks down into CO [deep] 2, which is stored in separate chambers and reacts back to SrCO [deep] 3 when required, giving off heat.
